The old approach required Lisp code to use (current-time)
explicitly when calling other primitives, e.g., (float-time
(current-time)). The new approach fakes all the primitives,
so that Lisp code can now use expressions like plain (float-time).
* testing/org-test.el (org-test-at-time): New macro.
* testing/lisp/test-org-colview.el (test-org-colview/columns-summary):
* testing/lisp/test-org-timer.el (test-org-timer/with-current-time):
* testing/lisp/test-org.el (test-org/org-read-date)
(test-org/deadline-close-p, test-org/deadline)
(test-org/schedule, test-org/time-stamp):
Use it.

Great, thanks! I'll go through all the spots where I've
s/nil/(current-time)/ for the sake of testing and restore nil.

Pushed (2cd1f9b028b) along with a follow-up commit removing current-time
calls that were kept for testing purposes.
